Cavansite  —Wagholi, Poona, India
Ex. Collection Christian Weise 
 
1.8 cm wide cavansite crystal in the rare and coveted sheaf-shaped crystal form. Unfortunately, the extraordinary and intense color cannot be shown on photos.In nature, the color is much more intense! Depending on the incidence of light, it changes from almost turquoise to an intense petrol blue. Beautiful aesthetic  piece from India with rare crystal shape.
